      [PATCH] NFS: large non-page-aligned direct I/O clobbers memory · e9f7bee1
      Trond Myklebust 提交于
      The logic in nfs_direct_read_schedule and nfs_direct_write_schedule can
      allow data->npages to be one larger than rpages.  This causes a page
      pointer to be written beyond the end of the pagevec in nfs_read_data (or
      nfs_write_data).
      
      Fix this by making nfs_(read|write)_alloc() calculate the size of the
      pagevec array, and initialise data->npages.
      
      Also get rid of the redundant argument to nfs_commit_alloc().

      [PATCH] ext3_getblk() should handle HOLE correctly · 3665d0e5

      It has been reported that ext3_getblk() is not doing the right thing and
      triggering following WARN():

      Looking at the code, it looks like it's not handle HOLE correctly.  It ends
      up returning -EIO.  Here is the patch to fix it.
      
      If we really want to be paranoid, we can allow return values 0 (HOLE), 1
      (we asked for one block) and return -EIO for more than 1 block.  But I
      really don't see a reason for doing it - all we need is the block# here.
      (doesn't matter how many blocks are mapped).
      
      ext3_get_blocks_handle() returns number of blocks it mapped.  It returns 0
      in case of HOLE.  ext3_getblk() should handle HOLE properly (currently its
      dumping warning stack and returning -EIO).
